cytokine signaling

Cytokine signaling is a communication process between cells in the immune system. Cytokines are small proteins released by cells that send signals to other cells, guiding them on how to respond to infections, inflammation, or injury. Think of cytokines as messages or alerts that help coordinate the body's defense mechanisms, ensuring that the right cells are activated at the right time. This signaling is crucial for maintaining health, as it helps the body fight off diseases while also controlling immune responses to prevent overreactions that could damage tissues.
